WASHINGTON – The CIA officer whose cover was blown by an alleged Bush administration leak and her diplomat husband have retained a Washington lawyer to find out who they can sue and how much money they can seek.

Also, the investigation, first focused on the White House and CIA, is now broadening to include the State and Defense departments, officials said.

“There’s no question that the Wilsons’ legal rights have been violated,” their lawyer, Christopher Wolf, told The Post. “More importantly, the country’s legal rights have been violated, and that’s first and foremost what they’re interested in.”

Wolf said he’s representing former Ambassador Joseph Wilson, who was sent by the CIA earlier this year on a mission to find out if Iraq tried to buy enriched uranium in Niger, and his wife, CIA analyst Valerie Plame, whose name was leaked to columnist Robert Novak.

The leak to Novak sparked a Justice Department investigation into allegations that someone at the White House may have leaked her name in order to punish Wilson for writing a column in the New York Times that The uranium-purchase claim was bogus.

Wolf said he doesn’t know how much money the Wilsons might seek or who they might sue. Asked if President Bush and Novak would be listed as defendants, Wolf said, “Nothing has been ruled out.”

White House spokesman Scott McClellan said he’s not aware that anyone at the White House has hired a lawyer or received a subpoena, meaning it appears that the first figures in the growing controversy to hire a lawyer are Wilson and Plame.
